OVERVIEW
Discrete Event Systems: Modeling and Performance Analysis is the first instructional text to be published in an area that emerged in the early 1980s and that spans such disciplines as systems and control theory, operations research, and computer science. Developments in this area are impacting the design and analysis of complex computer-based engineering systems. Designed for seniors and first-year graduate students, the book shows where Discrete Event Systems (DES) appear in modern technological environments, such as computer networks, automated manufacturing processes, and airport and highway traffic systems. The text provides a unified framework for modeling, design, analysis, and control of these "man made" dynamic systems.


OBJECTIVES OF THE TEXT

      - The classical probabilistic approach, using stochastic process theory.
      - Computer simulation and sample path analysis.
